Review on UPERFECT Portable 4K UHD Brightness FreeSync 15.6" Monitor, Frameless, Built-In Speakers, Glossy Screen, Model: MDS-156A23, HD by Tyrel Glass

I bought a UPERFECT 4K monitor to use with my band to display lyrics. I connect it to my iPad so the two band members can see the lyrics on the screen. I bought the monitor for its excellent picture quality, brightness and wide viewing angle. It was working great until recently when the charger started failing. I replaced it with another charger which solved the problem. I notified the manufacturer and they offered to replace the charger for free or give me a $30 refund to offset the cost of the charger I bought. I am very pleased with the manufacturer's quick response and willingness to resolve the issue. Overall I am very happy with my purchase!
